Scientist: Tell us what side effects the medication caused?
Test subject: my diabetes somehow is acting up again
Scientist: Oh
Wait, if it’s double-blind, wouldn’t the scientists be unaware of whether he got a placebo or the real drug? Although I suppose this could be after the study has concluded. I would bet that in real studies they record the side effects reported before checking to see if it was the placebo or not!
Downvoted for not knowing what double blind means.
Wrong answer: Researches who are blind in both eyes only give the medication to participants who are also blind in both eyes, thus making them unable to read the patient information leaflet.
Correct answer: It is a research design in which both the participants and the researchers are unaware of who is receiving the treatment and who is in the control group
